Object-detecting container apparatus

A blister pill pack container apparatus, comprising:

• a housing having a first side and a second side,
• the first side having a first end and a second end and the second side having a first end and a second end, the first end of the first side and the first end of the second side forming an enclosed end of the housing and the second end of the first side and the second end of the second side forming a closeable end of the housing,
• the first side having an exterior surface and an interior surface and the second side having an exterior surface and an interior surface, the exterior surface of the first side and the exterior surface of the second side forming an exterior of the housing and the interior surface of the first side and the interior surface of the second side forming a cavity, the cavity having:
• a sensor sheet attached to the interior surface of the first side and the interior surface of the second side, the sensor sheet comprising a flexible substrate and a first and second array of capacitive touch pads positioned on the flexible substrate, the capacitive touch pads of the first and second arrays comprising one or more layers of conductive material, the flexible substrate folded to arrange the first array of capacitive touch pads substantially parallel to the second array of capacitive touch pads with a space between the first and second array of capacitive touch pads for inserting a blister pill pack within the cavity;
• a printed circuit board (PCB) positioned between the sensor sheet and the interior surface of the first or second sides, the PCB comprising:
• a capacitive sensor driver chip coupled with the first array and the second array of capacitive touch pads, the capacitive sensor driver chip having a terminal to receive at least a first and a second capacitance signal from the first and the second array of capacitive touch pads;
• and
• a microcontroller configured to process a change between the first and the second capacitance signals to detect and measure movement of a blister pill pack sliding in to and out of the space.
